A microgrid can be considered a profitable solution to be adopted in smart cities if it is marketable, i.e. more, or at least equally convenient than other traditional energy supply sources. Different economic parameters can be defined to determine its affordability. In particular, the LCOE (Levelized Cost of Electricity) is the most popular indicator adopted in the energy sector, widely used both for conventional and renewable power sources. However, the use of this metric still disregards important aspects that concerns microgrid applications. After providing a state-of-the-art of the use of LCOE, the present paper proposes a new methodology for sustainable microgrids in smart city, taking into account benefits due to cogeneration and trigeneration, integration costs as well as positive and negative side effects.

The Subject

The lack of examples of smart-city initiatives and the sharing of best practices in Portugal confirm the gap in the transference of empirical knowledge to the scientific literature in this area. The smart-city concept has passed through three stages. However, its evolution has not been noted equally throughout countries and their territories. The literature only provides information about specific projects implemented in a few cities. Therefore, the aim of this paper was to study the state-of-the-art of smart cities in Portugal by analyzing 25 editions of the most relevant national-wide smart-cities magazine. First, the objective of analyzing the magazine was to study each Portuguese city in terms of the subject areas and types of existing initiatives in order, ultimately, to frame cities within their respective smart-city phases, as per the literature. Second, the aim of the paper was also to provide information about the evolution of the concept through analyses of embedded experts’ quotes. The results of the first are complemented with the analysis of interviews with policymakers to provide information about the existing challenges to implementing a smart city and to understand the role of government therein. Qualitative and quantitative analyses were performed on the case study. The findings suggest that the three smart-city phases are perceived in slightly different ways in Portugal and heterogeneity within the country can be noted from the lack of strategies and a standard framework.

Smart cities rely on smart technologies in all their possible forms; hence, this chapter is focusing on the state of the art of smart technologies. It describes these smart devices in all their ways and forms. In addition, techniques of software applications that are embedded in these smart devices are described along with their capabilities to adapt automatically and modify behavior to fit a user's environment. A smart city paradigm is also presented that focuses on sensors, smart devices, smart service provider subsystems, and smart sector infrastructure. A broader model of smart cities is discussed, and the chapter provides concrete goals, infrastructure, domains, and constituents. The chapter concludes by examining operation features such as the industrial setting, ubiquity, throughput, channels, and interoperability.

Abstract Nowadays, the transformations of metropolises into smart cities is a crucial factor in improving the living conditions of the inhabitants. The goal of the smart city concept is modern urban management using technical tools that offer state-of-the-art technologies, considering the applicable ecological standards while saving resources and achieving the expected results. The purpose of this article is to identify the areas of research analysed in the international literature in the field of smart cities. The bibliometric analysis was carried out to achieve the purpose. The analysis covered publications on smart cities published in Scopus and Web of Science databases from January 2009 to May 2019. Based on the bibliometric analysis, a bibliometric map was developed using the mapping technique VOS — the visualisation of similarities. Original clusters were created using the VOSviewer software. The bibliometric map visualises the results of the analysis that targeted the word coexistence.

Transparency And Accountability

Smart Assistants have rapidly emerged in smartphones, vehicles, and many smart home devices. Establishing comfortable personal spaces in smart cities requires that these smart assistants are transparent in design and implementation—a fundamental trait required for their validation and accountability. In this article, we take the case of Google Assistant (GA), a state-of-the-art smart assistant, and perform its diagnostic analysis from the transparency and accountability perspectives. We compare our discoveries from the analysis of GA with those of four leading smart assistants. We use two online user studies (N = 100 and N = 210) conducted with students from four universities in three countries (China, Italy, and Pakistan) to learn whether risk communication in GA is transparent to its potential users and how it affects them. Our research discovered that GA has unusual permission requirements and sensitive Application Programming Interface (API) usage, and its privacy requirements are not transparent to smartphone users. The findings suggest that this lack of transparency makes the risk assessment and accountability of GA difficult posing risks to establishing private and secure personal spaces in a smart city. Following the separation of concerns principle, we suggest that autonomous bodies should develop standards for the design and development of smart city products and services.

Modern cities are changing to become more reliant upon technology for better personal, social, and economic outcomes for all citizens. The core of enabling a smart city plan relies on a comprehensive understanding of its drivers and technological aid requirements. Hence, technology roadmapping as one of the most effective approaches need to be considered to aligning the smart cities strategies with planning in the field of technology, while the focus on the most technology roadmapping studies has been limited to the development of industrial technology and product development. Thus, to support the achievement of the smart cities, this study aims to adapt and utilise Strategic Technology Alignment Roadmapping (STAR) methodology to guid and justify investment in smart city’s R&D projects to achieve the optimum project portfolio. The method is tested in a real case study, which shows how STAR methodology can be effective to implement throughout the worldwide smart cities development to support strategic technology investments.

Definition Of

Technology is starting to play a key role in cities’ urban sustainability plans. This is because new technologies can provide them with robust solutions that are of benefit to citizens. Cities aim to incorporate smart systems in their industrial, infrastructural, educational, and social activities. A Smart City is managed with intelligent technologies which allow improving the quality of the services offered to citizens and make all processes more efficient. However, the Smart City concept is fairly recent. The ideas that it encompasses have not yet been consolidated due to the large number of fields and technologies that fit under this concept. All of this led to confusion about the definition of a Smart City and this is evident in the literature. This article explores the literature that addresses the topic of Smart Cities; a comprehensive analysis of the concept and existing platforms is performed. We gain a clear understanding of the services that a Smart City must provide, the technology it should employ for the development of these services, and the scope that this concept covers. Moreover, the shortcomings and needs of Smart Cities are identified and a model for designing a Smart City architecture is proposed. In addition, three case studies have been proposed: the first is a simulator to study the implementation of various services and technologies, the second case study to manage incidents that occur in a Smart City, and the third case study to monitor the deployment of large-scale sensors in a Smart City.

This paper presents the evaluation of usersХ experiences in three intelligent lighting pilots in Finland. Two of the case studies are related to the use of intelligent lighting in different kinds of traffic areas, having emphasis on aspects of visibility, traffic and movement safety, and sense of security. The last case study presents a more complex view to the experience of intelligent lighting in smart city contexts. The evaluation methods, tailored to each pilot context, include questionnaires, an urban dashboard, in-situ interviews and observations, evaluation probes, and system data analyses. The applicability of the selected and tested methods is discussed reflecting the process and achieved results.
